The Watchdog Timer (WDT) has a prescaler generating a timeout period. This prescaler is
clocked from the RC oscillator. The watchdog timer must be periodically reset by software within
the timeout period, otherwise, the device is reset and starts executing from the boot vector. This
allows the device to recover from a condition that has caused the system to be unstable.
When the WDT is enabled, the WDT remains clocked in all sleep modes, and it is not possible to
enter Static mode.
The WDT prescaler is frozen during debug operation, unless the OCD system keeps peripherals
running in debug operation.
The WDT can use the internal RC oscillator as clock source. This oscillator is always enabled
whenever these modules are active. Please refer to the Electrical Characteristics chapter for the
characteristic frequency of this oscillator (f
